Blavatsky
Original sense
The dynamic energy of cosmic ideation — the bridge between mind and matter, the ‘messenger’ that stamps the ideas of the Logos into primordial substance. She called it cosmic electricity, not as a metaphor for household current, but as the living force that builds worlds.
Fohat is the steed, and thought is the rider… it is the electric power of affinity and sympathy.
One of the few major cosmological terms she did not simply borrow from Sanskrit. New Age almost never uses the word; it uses ‘source energy,’ ‘chi,’ or ‘the universe sending signs’ to cover overlapping work.
